Massillon Wastewater Treatment Plant

The City of Massillon, Ohio retained CTI Engineers, Inc. to provide planning, design, and construction administration services for the expansion of its existing 12.5-MGD wastewater treatment plant. The upgraded plant (15.8 MGD) has been designed to serve the City of Massillon and portions of western Stark County for the next 20 years.

Flood Control Project Protects Cleveland's Largest Employer

When the Maytag manufacturing plant in Cleveland, Tennessee, was flooded in the spring of 2003, municipal leaders designated a flood protection project for the Woolen Mill Branch drainage basin as the City’s number one priority. Following aggressive funding efforts led by Congressman Zach Wamp, FEMA approved a $1.66 million grant for the project, with additional funds provided by the State of Tennessee.

CTI Updates Facilities Plan

“The plan update provides a great basis for moving the sewer program forward in a logical progression and projecting capital needs for the next 30 years.” —Jerry Stewart

CTI was engaged by the City of Chattanooga, Tennessee, to update the Wastewater Facilities Plan for the Chattanooga regional sewer system. The original Chattanooga, Tennessee-Georgia “201 Facilities Plan” was written in the 1970’s and provided the “blueprint” for one of the largest regional wastewater systems in the Southeast.

Citizens and CTI Address City-Wide Storm Water Issues

The City of Macedonia, Ohio is home to over 10,000 residents and scores of commercial and industrial businesses. Steady growth has resulted in the development of over 80 percent of the City’s 9.8 square miles of land, which generates a significant amount of storm water runoff. The City is responsible for maintaining over 44 miles of storm sewers, over 70 regional and single-site detention basins, and several waterways.

CTI Design Slashes Natural Gas Costs for Massillon WWTP

Twenty years after the last rebuild of the anaerobic digestion system at the City of Massillon’s wastewater treatment plant, this system was barely meeting minimal requirements. As a result of these problems, the City was forced to purchase large amounts of natural gas for digester heating. CTI was retained to design improvements to the sludge digestion facilities as part of a larger contract to expand the overall WWTP.CTI’s design included the following elements:

Chattanooga City Landfill Improvements

Like most municipal services, solid waste management has come under increased regulation in recent years in an effort to prevent ground water and surface water contamination. Many of us remember the old city "dump" as a place where garbage was simply pushed into a hollow at the edge of town. Today, landfills are highly engineered systems requiring sophisticated support facilities.

Storm Water Detention Structure Built Under Busy Thoroughfare

One of the busiest streets in Chattanooga is MLK Boulevard. This four-lane artery carries approximately 13,000 vehicles per day. Below the street is a combined storm/sanitary sewer. Following heavy rainfalls, the combined sewer facilities surcharged and the street became an open channel for excess flows. The City of Chattanooga hired CTI to perform an analysis of alternatives to eliminate surcharging in a seven-block area. The optimum solution was found to be construction of a storm water detention facility beneath MLK Boulevard.

New Membrane Water Plant In Hawkins County

For over 40 years, the First Utility District of Hawkins County has served the City of Church Hill and surrounding areas in upper east Tennessee. During that time, new service areas have been added and regulations governing treatment have become increasingly stringent. According to General Manager Allen Jones, these factors made it difficult for the District’s existing plants to be in regulatory compliance and to meet demand, especially in periods of insufficient rain.

Raw Water Intake Expansion

In 2005, the City of Cookeville, Tennessee, hired CTI Engineers, Inc. (CTI) to develop a long-term master plan for expansion of the City’s existing 15-MGD water treatment plant. The resultant study examined both conventional and membrane filtration alternatives. A water consumption demand of 22.5 MGD was determined as the needed capacity for the year 2025, and cost estimates were prepared for facilities sized to meet that demand.
